Specification or" Letters Patent No. 532,883, dated July 28, 1861.

To all whom it may concern:

Be it known that I, ALMERUN I. MERRILL, of Ypsilanti, in the countyY ofIVaShtenaW, and State of Michigan, have invented a new and usefulImprovement in Machines for Separating and Cleaning Threshed Grain fromthe Straw and Chart' and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which- Figure l is a perspective view of themachine. Fig. 2 shows the sieve and its attachments and Fig. 3, one ofthe reels separate from the machine.

In Fig. l A, A, A, A, shows the frame work of the machine. B, is apulley on the cylinder to which the belt from the ack is attached. C, C,C, is a series of belts communicating motion from the threshing cylinderB, to the reels D, D, &c., and so arranged as to give the reels auniform motion in the direction indicated by the arrow over the forwardreel. D, D, &c., is a series of reels, whippers or beaters used in placeof a saddle, or a canvas or lattice work belt to carry forward the strawand at the same time shaking out loose kernels of grain. E shows theposition of the fanner. F shows the end of the inner shaft carrying thelattice or wheat belt. Gr shows the end of the wheat screw, and H theend of a tailings screw. I, I, I, is a series of belts deriving motionfrom the fanner and moving the wheat belt, and wheat and tailingsscrews. J is a cover overlying the reels, &c. K is an opening throughwhich the straw passes to the thresher, upon the reels, whippers orbeaters. X is the feeding point and Z the lower floor, inclosing fanner,screws, &c. Y is the wheat belt-having a motion on its upper surface asindicated by the arrow upon it.

In Fig. 2, N shows part of the fanner shaft, being the opposite end fromthat seen in Fig. 1. There is a pin in the opposite side of the pulley4L on which a crank is made and to which the pitman O, is attachedcommunicating motion to the crank P of the rock shaft Q. R, R, are twoshake wheels or cranks, which by the pitmen U, U, give motion to thesieve T. S, S, S S are the hanging blocks and rods of the sieve T. V isa tailings screw-working out the tailings at an orifice in the side ofthe machine at the end of the screw IN. The rods of the sieve hangingsS, S, S, S, are made fast in the sieve and in the blocks, and arehammered thin in the middle so as to spring, so no motion is lost.

In Fig. 8, L, shows the center shaft of one of the reels, M, M, thewheels or rims at the ends upon which are placed the four rods making upthe reel. Fig. 4 represents a longitudinal vertical section of a portionof the machine in which the relative positions of the several partshereinafter claimed in arrangement are seen.

The operation of the machine is substantially as follows: The machinebeing arranged and put up in the manner already described, is fed at thepoint X, Fig. l, the straw comes at once upon the reels D, D, &c., whichhave a common motion forward upon the upper surface, and beingconstructed in the manner shown readily carry forward the straw butallow all loose grain to fall below, and do not carry or throw the grainover. The wheat or lattice belt Y, passes around a stationary bottom andwhich is inclined inward toward the rock shaft and rake Q-the inner endbeing over the sieve T. The wheat or grain passes down this stationarybottom, inclined as stated and falls upon the sieve which has a back andforward, end motion, and is in the current from the fanner. The rake androck shaft at the same time constantly toss up the short straw and cha',at once shaking out the grain, and exposing the chaff and straw to beblown away. The sieve has an end motion, and is so arranged that the endnext the rake is the lowest-thus preventing the grain working over thefront end. lhatever heads contain wheat are blown to the front edge ofthe sieve, and carried out by the tailings screw V and again returned tothe thresher by apparatus not shown in the drawings, and not needed aspart of this specification. By this arrangement the shoe of the sieve isdispensed with, and the sieve is so placed and so moved that much lesswheat or grain is thrown over and lost. The sieve is hung in the mannerdescribed,

and moved by the pitmen as shown in Fig.

2, which allows the inclination of the sieve to be toward the rake, andfanner as it should be, and secures a much more satisfactory and uniformmotion. In the commore effective in cleaning-and, at the saine timethere is a saving of one horsepower in Working it When the Weight of theshoe is removed.

I donot claim any of the devices herein named separately 'andindividually as they are not new but That I do claim is- A Arranging thereels D, D, D, the endless grain carrier, the rake Q, the Sieve T, andthe screw conveyers V, together in the man ner herein represented Whenthe Several parts are connected and made to operate as specified.
